I'm not a good programmer but wouldn't it make more sense to create already some standard text formats for headlines like
At the moment a class in h1 is used which looks a little bit dirty to me.
<h1 class="_Header2">Headline 2<h1>
Also I'd really appreciate if it'd be possible to add custom css to the text formats. Borders, text-shadows, background color... All this would be much easier to edit with a custom CSS field.
